Combining rules: Difference between revisions

Revision as of 15:19, 22 November 2007

The combining rules (also known as mixing rules) for binary mixtures are variously given by

\epsilon _{ij}={\sqrt {\epsilon _{ii}\epsilon _{jj}}}

\sigma _{ij}={\frac {\sigma _{ii}+\sigma _{jj}}{2}}

(Ref. 2)

(Ref. 3)

For the second virial coefficient of a mixture (Ref. 2)

B_{ij}={\frac {\left(B_{ii}^{1/3}+B_{jj}^{1/3}\right)^{3}}{8}}
